Hmmm. One way around it is to define the subspace generated by what we know is a basis. That will work: gap> G := Subspace(F, b); <vector space over GF(5), with 7 generators> gap> Dimension(G); 7 gap> Basis(G, b); Basis( <vector space of dimension 7 over GF(5)>, [ !Z(5)^0, (a), (a^2), (a^3), (a^4), (a^5), (a^6) ] ) All the best, Erik. _______________________________________________ Forum mailing list [email protected] http://mail.gap-system.org/mailman/listinfo/forum
